Background: To identify the difference of surgical margin and recurrence status of early stage tongue carcinoma via wide excision in a single institution with and without free flap reconstruction. Objective: Survey whether the reconstruction methods for early tongue cancer affects disease control, survival outcomes. Methods: This was a retrospective study and patients with early tongue cancer underwent surgery via tumor ablation with (group 1=56) or without free flap reconstruction (group 2=291). Results: The percentage of patients with free margin less than 5mm was higher in the group 2 than in group 1 (49.48% vs. 19.64%, p<.001), as the mean free margin was significantly larger in group 1 than in group 2 (7.88mm vs. 5.68 mm; p<.001). Despite higher number of T2 stage patients in group 1 (89.29%), the group 1 resulted in a significant lower recurrence rate (p=.024). Conclusions: The utilization of free flap reconstruction for early stage tongue cancer achieved a large pathologic free margin and had relative lower recurrence and good survival rates.
